Super Heterodynes.

N page 19 of the "New Zealanil | Radio Listeners’ Guide," there are several statements made with regard to super heterodyne receivers, on which we should be glad to be allowod to comment, A statement is made to the effect that "Super-heterodynes take a large tunount of both high and low tension current, so that wet batteries would be almost imperative. To show that these remarks are not applicable to all superheterodynes, we give herewith the filament and plate current taken on three of our most popular super-heterodynes : Radiola 26 (six-valve set), filament current, .36 amp.; plate current, 10 milliamps, Radiola 25 (six-valve set, employing a power tube), filament current, A2; plate current, 12 milliamps. Radiola 28 (8-valve super-hetero-dyne, employing a power tube), filament current, .54; plate eurrent, 17.5 milliamps. The final paragraph, dealing with the super-heterodynes, does not apply to any of the seven models handled by us, as they are all licensed hy the Post and Telegraph Department for use On an outside aerial.-Amalgamat-ed Wireless (Australasia), Ltd,
